Which vаlue is а vаlid sоlutiоn tо the system of inequalities shown in the graph? "The x-axis and the y-axis span from below negative 5 to above 5. Both axes show intervals of 5 with grid lines in increments of 1. The red diagonal line with a negative slope has an x-intercept of (3, 0) and a y-intercept of (0, 6), while the area above is shaded red. The dashed blue diagonal line with a positive slope has an x-intercept of (1, 0) and a y-intercept of (0, negative 1), while the area below is shaded blue. The two lines intersect at a coordinate with x value roughly halfway between 2 and 3 and y value roughly halfway between 1 and 2. Their corresponding shaded areas overlap to create a purple-shaded area, spanning the first and fourth quadrants. "
